It doesn't cause any problems, I've just been sticking to drinking water. I'd rather not sell it on eBay and just give it to someone instead. This is a good thing to have for families with children that want to drink "soda" since it's a treat that many kids demand, haha.

I have one and I love mine. Love to add some fresh juice and stevia and ice. I puree fresh ginger with water and stevia, vanilla and a pinch of salt...then dilute with carbonated water. Make a chocolate syrup with water, cane sugar and cocoa..recipe in book..anyone can post it..I forgot the page. Anyway, add some ice, a little whole organic milk and carbonated water..chocolate soda! It's great with just powdered ginger, sugar, and vanilla. My husband loves it with just a squeeze of orange juice and lemon...no sweetener..very refreshing. I like to add fresh mint to it.

I use 1 oz in about 10 or more oz of water so it is about half the strength of juice.

I also like pomegranate soda - same recipe.

I have tried blueberry too but it doesn't mix well but isn't bad if I do half cranberry and half blueberry. Cranberry alone is a little too tart but I have drunk it when I need to push cranberry juice for a bladder problem.

I just prefer the cherry and the pomegranate sodas as well as the lemonade / limeades.

I got the Soda Stream as I was drinking carbonated water daily to settle my stomach and was tired of the high prices (live in a tourist trap so seltzer can be pretty high at the store) and having all the bottles to recycle. It will also save money in the long run. I order the replacement tanks online but now Staples sells them too.

Ada, I would use it - that sounds fun and my teen and his friends would get a kick out of it! We spend way too much money on Zevia in the summer. But if anyone else wants it, no biggie. If it is still available let me know at lstroyan at gmail dot com and I can send you $ for shipping.

If I didn't have one already I would have been a taker myself. I opted to let someone else have it who wouldn't have one otherwise.

The bottles you replace every 3 years - I don't need more than the 2 that came with it right now. The CO2 tanks you do need to replace / exchange but I just had gotten an order for those and am covered for a year. The tank would have been the only reason for me to get your machine as the machine itself seems fairly sturdy.
